To all whom it may concern:

Be it known that I, ARNOLD MAN, a citizen of the United States, residing at Detroit, county of \Vayne, State of Michigan, have invented a certain new and useful Im movement in Syringes, and declare the following to be a full, clear, and exact description of the same, such as will enable. others skilled in the art to which it pertains to make and use the same, reference bein had to the accompanying drawings, whic l form apart of this specification.

This invention relates to vaginal syringes, and has for its object an improved syringe of Sllll lo and economical construction, that is'easi y separated into its constituent parts for packing, and cleansing, is convenient for use, and has means whereby the cleansing fluid used with it is discharged in a diverging or spreading sheet, not broken upon into dmwcrous streams or masses, and is recov erct into the bulb of the syringe without soiling either the body or the clothing of the user.

In the drawings :--Figure 1, is aside elevation of the entire s ringe. Fig. 2, is a section on an enlarge scale, showing the nozzle. Fig. 3, is a section on anrnlarged scale, showing thebulb connection.

The bulb made from elastic material, preferably rubber, is provided with a thickened rim 2 that is expanded over the'flange 3, and contracts into the neck 4 of a coupling 5 of hard rubber. The coupling 5 inter nally screw threaded; the nozzle 6 is provided with a screw threaded terminal that engages in the coupling .5v The coupling between the nozzle and the bulb, is readily disen w ed and read access to the bulb is possi le at. all tunes for the purpose of cleansing the interior of the bulb. The noz zle is'prferably a solid piece of hard rubber, Having a slight angle or bend intermediate its extremities, and. is provided with a flexible rubber shield 7 that engages at any convenient oint along the tube, and is held thereto By a contractile terminal of the flexible material of which the shield 7 made. The delivery end of the nozzle is rovided with a chamber 9 of slightly arger bore than that of the main body of thenozzle; within the chamber 9 is located. a check valve 11, whose valve part 12 is made in the form of a cone, and is ada ited to engage against a seat 13 on the dc ector plug part of the nozzle 14. The deflector part Specification of Letters Patent. Application filed March 16, 1808. Serial No. 421,373.

of the nozzle is a plug provided with a screw threaded flange 15, by meansof which the plug engages in the outer end of the nozzle, and is adjustable with respect to the rim 19 at the delivery end of the nozzle.

The flange 15 is provided with a number ot'fby-pzissages 16 through which the liquid is forced in its-discharge travel; to reach these by-passcs the liquid travels througl'i perforations 1.7 in the wails of the check valve '12; from the by passages the liquid travels torwari'l against a conical expanding or deflecting ring 18 on the plug. This conical expanding or deflecting ring extends opposite and parallel to the rim 19 of the nozzle, and causes the fluid which is forced through the nozzle and out through the aunular passage between thedeflcctor and the- .the check valve 12 is drawn back or forced back consequent to the relaxation 'of the pressure on the bulb, but which is closed when the bulb is compressed and the fluid contained in it forced outward through the nozzle.

1. In a syringe nozzle, the comlnnation of a tubular conduit, a deflecting plug having a screw threaded portitm. adapted to engage within a. compien'ientary portion of the con.- duit and a conical terminal portion extending across the end of aid'conduit, there being a central aperture and a plurality of bypassagcs extruding lengthwise of 'said conduit through the body of the plug, and a slotted check valve slidably arranged 'within said conduit, through which the lluid ejected from the syringe pas without change in its direction of lion, jetted, to the forward limit of its travel serving as a. closure to said central aperture, substantially as dcscrilicd.

lion of a tubular coi'idnit. a dcllectihg plug havin a. central passage, inserted in the end aid valve when pro.

' through the conduit must member hm'ing a'centz'al aperture adapted to expelled from the syringe bulb passes,

adapted to close said central passage in the deflecting plug, substantially as described.

3. In a syringe, in combination with a conduit member, a valve member slidable therein and through which all fluid passing pass, and .a plug be closed by the engagement of said valve thereabout, and a deflector member th ere agail'xst, a plurality of by-passages arrange member integral with the aperfiured portion and extending across one end of said conduit member, being slightly spaced tl1erefr01n, sl lbstantially as described. In'tesbimony wherecf, I sign this specification in the presence of two Witnesses.
